I think it would be better than 2.5D (displacement from z-map) and more like 2.8D or so. Because deep samples are literally on top of each other.
Not all renderer seem to be equal in terms of samples per pixel but Mantra seems to be the most generous especially for heterogenous volumes, compared to Arnold. And I think it would be much faster if I could devise a deep NDK operator that could do that instead of redendering or rendering 2 frames both computationally and in terms of storage. Plus, you would get maximum compositing flexibility as well. > On Oct 30, 2014, at 7:30 PM, Elias Ericsson Rydberg > <[email protected]> wrote: > > I'm thinking that you could render one deep frame from 3D.
